Summary The first record of Andrena florivaga Eversmann, 1852 is reported from Poland on the basis of specimens collected in the Kampinos National Park (Mazovian Lowland). Diagnosis, data on localities, biology, and general distribution of the species are provided. One female and five males were caught on a mowed fresh meadow and fallow fields with the use of water pan-traps (Moericke traps), during the 2003 - 2004 time period. The main morphological characteristics distinguishing Andrena florivaga from the very similar Andrena dorsalis Brullé, 1832 species and from the other species of the subgenus Lepidandrena are: in the case of females - the width of facial foveae and colouration of legs, and in the case of males - the length of the first flagellar segment, colouration of clypeus, and pubescence of gonostyles. Andrena florivaga can be found from France in the west, to Central Siberia (Baikal lake region) in the east, and Turkey in the south. Poland is the northernmost locality of the species.

Semantic Aspect

The purpose of this article is to give detailed description to all possible semantic and morphological features of Germanic preterite-present verbs. Some research has dealt with the problem of preterite-present present verbs; however, semantic and morphological functions of these verbs were studied only by singling out verb characteristics, peculiarities, potential possibilities in different Germanic languages without any alignment of the obtained results. There is little information available on preterite-present verbs within the west Germanic and North Germanic (Scandinavian) subgroups. Semantic aspect of these verbs was analysed by some scholars, but it is still unknown how these verbs were formed in other Indo-European languages (Baltic, Slavonic, Romantic). The contradicting point of the available research is how those verbs are reflected in Latin and Greek. In spite of the fact that preterite-present verbs were studied in detail in terms of phonological characteristics, their morphological and semantic peculiarities were not taken into account and compared. Special attention should be given to the functioning and correlation of phonological and morphological peculiarities of those verbs. This paper offers the results of a detailed and consistent analysis of phonological and morphological peculiarities of preterite-present verbs. The paper aims at determining the morphological characteristics of preterite-present verbs, which were formed under the influence of phonological processes. The purpose of this study was to investigate the connection of Germanic preterite-present verbs with possible sources in other Indo-European languages. The authors define a set of characteristics peculiar of preterite-present verbs semantics. The functions of these verbs are analysed in detail. The authors attempt to analyse the nature of these verbs. The attention is paid to the functions of preterite- present verbs not only in the Germanic languages, but in other Indo-European languages, too. The comparative historical method is used here as the main one. The authors see this valid way of investigation as reliable and appropriate for the preterite-present verb analysis.

Occurrence, distribution and pathogenicity of Fusarium spp. associated with roots and rhizosphere soils of forest trees were studied. Fusarium spp. was isolated from phloem and sapwood of forest trees and composite rhizosphere soil samples collected from highly diversified geographical and climatic regions of the west of Iran and identified based on their morphological characteristics. Only three Fusarium spp. (F. oxysporum, F. solani and F. eumartii) was isolated from roots. F. nygamai, F. graminearum, F. scirpi, F. proliferatum, F. anthophilum, F. longipes and F. chlamydosporum were recovered from soil samples collected from warm and moderately warm regions, while F. culmorum, F. sporotrichioides, F. sambucinum and F. subglutinans were recovered from cold regions. F. solani, F. oxysporum, F. semitectum, F. equiseti, F. verticillioides, F. merismoides and F. avenaceum were present in all climatic regions. In the bark inoculation tests, selected Fusarium strains representing all species were evaluated for their pathogenicity on stems of healthy Prunus amygdalus under greenhouse conditions. Stem rot assessment revealed that F. oxysporum, F. solani and F. eumartii were the most damaging species.

Two cultivars of chokeberry - ‘Nero’ and Polish ‘Galicjanka’ are sold in Poland. Sometimes, there are also present the seedlings of ‘Viking’ and ‘Hugin’ cultivars. In the experiment some morphological characteristics, the quality of fruits and chemical composition of four chokeberry cultivars (‘Galicjanka’, ‘Hugin’, ‘Nero’, ‘Viking’) were compared. Chokeberry plants were grown at the Experimental Station of Pomology Department at the West Pomeranian University of Technology in Szczecin. Fruits collected from ‘Hugin’ cultivar shrubs were the smallest (100 fruits weight was 32 g) and the least juice was obtained from them (73.6%); however, they were characterised by the highest content of soluble solids (18.7°Bx), titratable acids (1.05 g), polyphenols (2340 mg), especially cyanidin 3-galactoside as well as nitrates (98.5 mg) and nitrites (1.87 mg). The ‘Hugin’ cultivar was characterised by light-coloured fruits, and, as a result, by light-coloured juice. Fruits of ‘Galicjanka’ cultivar were the biggest, 100 fruits weight was 111,7 g. In fruits of the ‘Nero’ and ‘Viking’ cultivars, the content of individual components was at the lowest level. These cultivars have the largest amount of substances colouring fruits, pulp as well as red and blue juices, are also the darkest and the dark juice was obtained from them. Maceration of fruit pulp resulted in a significant change of colour of the juice obtained, it become darker and had a more intense blue colour.

Barnacles of the genus Chthamalus are commonly encountered rocky intertidal shores. The phylogeography of the different species in the Western Indian Ocean is unclear. Using morphological characteristics as well as the molecular markers mitochondrial cytochrome oxygenase subunit I (COI) and the nuclear sodium-potassium ATPase (NaKA), we identified four clades representing four species in the Western Indian Ocean and its adjacent seas. Among these species, a newly identified species, Chthamalus barilani, which was found in Madagascar, Zanzibar and Tanzania. Chthamalus from the coasts of Tanzania and Zanzibar is identified morphologically as C. malayensis, and clusters with C. malayensis from the Western Pacific and the Indo Malayan regions. C. malayensis is regarded as a group of four genetically differentiated clades representing four cryptic species. The newly identified African clade is genetically different from these clades and the pairwise distances between them justify the conclusion that it is an additional cryptic species of C. malayensis. This type of genetic analyses offers an advantage over morphological characterization and allowed us to reveal that another species, C. barnesi, which is known from the Red Sea, is also distributed in the Arabian Sea and the Persian Gulf. We could also confirm the presence of the South African species C. dentatus in the Mozambique channel. This represents the Northeastern limit of C. dentatus, which is usually distributed along the coast of southern Africa up to the Islands of Cape Verde in West Africa. Altogether, based on a combination of morphology and genetics, we distinct between four clusters of Chthamalus, and designate their distribution in the West Indian Ocean. These distinctions do not agree with the traditional four groups reported previously based merely on morphological data. Furthermore, these findings underline the importance of a combining morphological and genetics tools for constructing barnacle taxonomy.

The taxonomic position of the population of tree-like, mostly polycormic individuals of pines from the Mshana peat bog in the Gorgany Mountains (East Carpathians, Ukraine) has been studied on the basis of the morphological characteristics of cones and needles, and anatomical characteristics of the needles. These features have been compared with the surrounding <em>Pinus mugo</em> population as well as <em>P. uliginosa</em>, <em>P. mugo</em>, <em>P. sylvestris</em> and <em>P. uncinata</em> from natural populations of the taxa. Tree-like individuals were found to have the most similar needles to <em>P. uliginosa</em>, but most similar cone characteristics to <em>P. mugo</em>. It was concluded, that the tree-like population has a relic character and can present the trace of the early migration of <em>P. uliginosa</em> from the West and its hybridisation with <em>P. mugo</em>.

SummaryThe Muturu, a trypanotolerant cattle breed is probably one of the least known breed of cattle in West Africa. Little has been published on its distribution, management, morphological characteristics or biological performance.Early reports showed that the Muturu cattle were once widely distributed across the continent from Liberia, across the West African subregion, to Ethiopia. However, due to expansion of the Zebu population and rapid urbanization, the small bodied animal came under pressure and was found surviving in pockets of the savannahs and in the humid forest zones where it had the comparative advantage of trypanotolerance. The survival of the cattle in the humid and forest zones of Nigeria stems from the fact that the animal is still sacred in so many communities and its milk is widely used for medicinal purposes. In some states of Nigeria, the semi-feral Muturu are not tended but hunted when required for sacrifice.From a population size of 0.4 million heads in 1960, Akinwunmi and Ikpi, (1985) reported a decline in the population of the breed to 50–80 thousand in the late 1980s in Nigeria although RIMS (1992), reported a population growth to 115 172 heads. With limited data bank information on their adaptation and productivity, possible identification of genes that confer resistance to or tolerance of environmental stress in these animals will be of global significance.
